How to Add Sui to MetaMask
Summary: Sui can be connected to MetaMask through the Sui Snap, a community-built extension that creates a dedicated Sui address inside your existing wallet.
MetaMask has added native support for Solana, Bitcoin, and TRON, but Sui is not on that list, so the Snap remains the only direct option.
The Snap handles basic transfers, staking, and dApp connections, though it runs on desktop only. For complete coverage of the ecosystem, a dedicated wallet like Slush or Phantom is the better long-term setup.
MetaMask Snaps Overview
MetaMask Snaps are opt-in extensions that let MetaMask support non-EVM networks like Solana and Sui and even manage Bitcoin, alongside standard Ethereum apps.

Can I Add Sui to MetaMask?
Yes, you can connect Sui to MetaMask by installing the Sui Snap from the official Snaps directory. Sui runs on the Move programming language with an object-based data model rather than the account model used by the Ethereum Virtual Machine, so it cannot be added through RPC details the way a standard network can.
MetaMask has been expanding beyond Ethereum, with Solana and Bitcoin now built directly into multichain accounts. Sui has not received that treatment yet, which leaves the Snap as the only way to use the network from inside MetaMask.
How to Add Sui to MetaMask
The Sui Snap was built by Kuna Labs with a grant from the Sui Foundation. It is open source under the Apache-2.0 license and has been audited by Sayfer, giving it stronger credentials than most third-party Snaps.
Follow these steps to install it:
- Open the Snaps Directory: Visit the Sui Snap page on the official MetaMask Snaps store.
- Click 'Add to MetaMask': Start the installation from the top of the Snap's listing.
- Review Permissions: Check the access the Snap requests, then approve it in your MetaMask wallet.
- Connect Your Account: Go to suisnap.com and click 'Connect' to generate your Sui address and open the wallet interface.
- Fund the Address: Send SUI from an exchange, or move assets across with one of the best crypto bridges, and you are ready to transact.
What the Sui Snap Can and Can't Do
The Snap covers the essentials: sending and receiving SUI and Sui-based tokens, staking, NFT management under the Sui Kiosk standard, and signing into dApps that have integrated it, such as Cetus and Typus.
There are real limitations to understand before relying on it. The Snap generates a separate Sui address rather than reusing your Ethereum one, and your Sui balances appear on the suisnap.com interface instead of the main MetaMask screen. It only works in the desktop browser extension, so there is no mobile access, and a portion of Sui dApps still list only native wallets in their connection menus.
Best Sui Wallet Alternatives to MetaMask
If you want full ecosystem access, these wallets are purpose-built for Sui:
- Slush: The official wallet from Mysten Labs, formerly known as Sui Wallet. It supports staking, in-app swaps, NFT transfers via shareable links, and zkLogin sign-in with a Google or Apple account, available on browser and mobile.
- Phantom: A leading multichain wallet covering Sui alongside Solana, Ethereum, Base, and Bitcoin. Enable the Sui network in settings to manage SUI, NFTs, and dApps like Suilend and Bluefin from one app.
- Suiet: An open-source, Sui-first browser extension with token management, staking, and broad dApp compatibility, suited to users who want a lightweight dedicated option.
- Ledger: A hardware wallet with native SUI support in Ledger Live. It pairs with Slush or Suiet for cold storage of larger positions while keeping private keys offline.
About Sui
Sui is a Layer 1 blockchain from Mysten Labs that uses the Move language and an object-centric model to process transactions in parallel, with its Mysticeti consensus delivering sub-second finality. The same Move foundation powers Aptos, though the two chains implement it differently.
The network has built serious institutional momentum through 2026. Three US staking ETFs from Grayscale, Canary Capital, and 21Shares listed in February, CME Group added SUI futures as only the fourth Layer 1 on its platform, and DeFi value locked has climbed past $2 billion alongside more than $1 trillion in cumulative stablecoin transfers.
Bottom Line
The Sui Snap is a practical bridge if you live inside MetaMask and want occasional access to Sui without installing anything new. It is audited, free, and handles transfers, staking, and major dApps from the wallet you already trust.
For anyone active on the network, a dedicated wallet wins on coverage. Slush delivers the full official feature set, Phantom suits multichain portfolios, and Ledger adds hardware security for long-term SUI holdings.
